Abstract
Humic substances are shown to photosensitize transformations of several types of synthetic chemicals that do not photoreact when exposed to sunlight in distilled water. In most cases, photoproducts were the same in colored natural waters and in solutions of soil-derived humic substances, including those obtained commercially. Kinetic studies in sunlight indicated that the efficiencies of the reactions photosensitized by humic substances of various origins were the same within a factor of 2.
